I have the PA 1x SLX prism and use a Holosun 3x magnifier with it. Both have a diopter
I set the diopter of the 1x prism 1st, and then the magnifier. I like this setup a lot. It's on my house gun.
It's unconventional, but for this setup, I prefer the magnifier in front of the optic vs the normal behind the optic. Allows for a much greater eyebox, easier to actuate and doesn't magnify the reticle. Getting the distance between the magnifier and prism optimal is the challenge.
